Milgauss
Oyster, 40 mm, Oystersteel
This Oyster PerpetualMilgauss features a Z-blue dial withluminescent hourmarkers, a greensapphire crystalproduces lightreflections whilepreserving optimallegibility.
With its clean lines and evocative orange seconds hand,
shaped like a lightning bolt to echo the original model, the
Milgauss is recognizable at a glance.
Green sapphire crystalA secret process
The green sapphire crystal is a unique watch crystal
developed by Rolex, it is scratchproof, fade-proof and
available exclusively on the Milgauss.
Z-Blue DialAn emblematic allusion
Green sapphire crystal marked a first in watchmaking
when it was introduced on the Milgauss in 2007. Now this
crystal is combined with an electric blue dial, an allusion to
the emblematic lightning-bolt-shaped seconds hand.
OystersteelHighly resistant tocorrosion
Rolex uses Oystersteel for its steel watch cases. Specially
developed by the brand, Oystersteel belongs to the 904L
steel family, alloys most commonly used in high-
technology and in the aerospace and chemical industries,
where maximum resistance to corrosion is essential.
Oystersteel is extremely resistant, offers an exceptional
finish once polished and maintains its beauty even in the
harshest environments.
The Oyster braceletAlchemy of form andfunction
The design, development and production of Rolex
bracelets and clasps, as well as the stringent tests they
face, involve advanced high technology. And, as with all
the components of the watch, aesthetic controls by the
human eye guarantee impeccable beauty. The Oyster
bracelet is a perfect alchemy of form and function. First
introduced in the late 1930s, this particularly robust and
comfortable metal bracelet with its broad, flat three-piece
links remains the most universal bracelet in the Oyster
collection.
An Efficient ShieldingSystemResistence to magneticfields
The first innovation at the heart of the Milgauss' resistance
to magnetic interference is the shield inside the Oyster
case. Made of ferromagnetic alloys selected by Rolex, it
surrounds and protects the movement. The symbol for
magnetic flux density – the capital letter 'B' with an arrow
– is engraved in this magnetic shield, but only Rolex-
certified watchmakers will ever see it.
3131 MovementSuperlative performance
The Milgauss is equipped with calibre 3131, a self-winding
mechanical movement entirely developed and
manufactured by Rolex. It incorporates state-of-the-art
technologies patented by the brand that ensure
exceptional resistance to magnetic fields. Like all Rolex
Perpetual movements, the 3131 is a certified Swiss
chronometer, a designation reserved for high-precision
watches that have successfully passed the Swiss Official
Chronometer Testing Institute (COSC) tests. Its
architecture, in common with all Oyster watch movements,
makes it singularly reliable.
